Synthesis and electroluminescence properties of diazocine derivatives with different positions of naphthyl group |
| 초록 |
The new diazocine derivatives, 1-DAN and 2-DAN have been successfully synthesized and characterized. 1-DAN and 2-DAN, are different the positions of naphthyl substituted in the anthracene. 1-DAN and 2-DAN showed absorption in the range of 354 to 402 nm in the film state and exhibited blue photoluminescence (PL) emissions at 441 and 450 nm, respectively. The PL wavelength of 1-DAN was blue-shifted by 9 nm than that of 2-DAC. This is because the conjugation length is decreased by H atom-H atom repulsion between 1-naphthyl and anthracene. Organic light emitting diode (OLED) device using 2-DAN as emitting layer (EML) showed current efficiency of 1.76 cd/A. |
